Desktop Packager License Question - One License - Three Platforms?

Sencha,

I am a little bit confused with your licensing system. As per your license, if more than one developer is working then I will have to acquire license for each. But I can use the same license to register the application in multiple operating systems?

I am saying multiple operating systems because currently I am evaluating the Mac version of Desktop Packager on my Mac. But I want to package my application for Windows and Linux as well. I plan on running the Desktop Packager on a Virtual Windows and Cent OS machine for the purpose of packaging only.
